In this item, we calculate first for the price of each can of coffee by dividing the cost by the number of cans of coffee.
Price per can = cost / total number of cans of coffee
price per can = ($2.40) / 4 = $0.6/can
To compute for the price of the 1/4 can, multiply the price by can by 1/4.
price of 1/4 can of coffee = (1/4 can)($0.6/can)
price of 1/4 can of coffee= $0.15
Therefore, the 1/4 can of coffee will cost only $0.15.
